Mastic can also be used to seal expansion joints in the concrete decking, patios, driveways, sidewalks or any concrete joint. Unsightly plastic dividers can be removed and mastic put in its place.
Vertical mastic can be used on pools with cantilever decking. the joint between the waterline and the concrete decking can also be sealed with mastic. Commercial swimming pools need mastic maintenance to be in compliance with the local health department.
The mastic sealant can be a Deck-o-Seal product made for swimming pools or a Sika Flex product which comes in a variety of colors for custom concrete.
Sanded mastic with just the right touch can give the mastic a more natural and pleasing affect instead of a rubbery look.
